Question

A 35 year old firefighter is ascending stairs at a rate of 3 1/2 floors/min with full equipment weighing 8lbs. (Includes the SCBA with 57.3 L of O2). Evidence suggests this work is = ~12 METS on average. According to recent testing his VO2 max= 5.45L/min, he weighs 200 lbs, and he has 10% body fat. 10 years later.. Absolute VO2max decreases 20% and he gains 30lbs of fat. (3 lbs/year) 1. What is his new relative VO2 max? 2. What is the new relative intensity at 3 1/2 floors/minute? Is this even possible? For how long? Expected HR? 3. If he wants to lose body fat, at what intensity should he perform his daily 30 min. cardio at and why? 4. How many pounds of fat does he have to lose to get to a healthier 15% body fat ? 5. Provide him a safe and effective BASIC exercise description (Rx) that is EVIDENCE BASED for; aerobic, muscular, and flexibility training, so he can regain some fitness.

Explanation / Answer

METS simply means metabolic equivalent. It is used to estimate used by body during physical activity. 1 MET= 3.5 ml/kg/min

230 x15%= 34.5 lb , now he has 50 lb so he has to loose 15.5 lb of fat.
